options('huxtable.add_colnames') sets the default value for add_colnames in
huxtable() and as_huxtable(). If it is unset, add_colnames defaults to
FALSE; in a future release, the default will become TRUE.
options('huxtable.print') sets the print method for huxtable objects. See print.huxtable().
options('huxtable.knitr_output_format') overrides the default output format when huxtable
objects are printed by knitr. Set to "html", "latex", "md" or "screen". If NULL (the default),
huxtable guesses the format using guess_knitr_output_format().
options('huxtable.color_screen'). If TRUE and package crayon is available, huxtables
will be printed in color on screen.
options('huxtable.knit_print_df'). If TRUE (the default), data frames in knitr will be
pretty-printed using huxtable.
options('huxtable.knit_print_df_theme'). A function applied to data frames
before printing in knitr. The function should take one argument (a data frame) and return a
huxtable. Defaults to theme_plain().
options('huxtable.autoformat') sets the default value for autoformat in huxtable() and
as_huxtable(). It defaults to TRUE.
options('huxtable.autoformat_number_format') and options('huxtable.autoformat_align') are
lists. The list names are base R classes. huxtable() with autoformat = TRUE will set
number_format() and align() for data columns according to the corresponding list values.
For example, to center-align Date objects you could set "huxtable.autoformat_align" to
something like list(..., Date = "center", ...).
